SPINDLE-DRIVING MECHANISM.

Application filed September 10, 1927. Serial Ito/218,630.

My present invention relates to improvements in spindle driving mechanisms suchas used for imparting rotary motion to spindles of spinning machines and is especially adapt ed for use on that type of spinning machine disclosed in patent to D. Pease, No. Lilo-323b, Fel 25, 1913, in which the traverse of the yarn on the bobbin is eil'ectcd by the reciprocating movements of the spindle rail.

this of the objects of the invention is to provide a construction whereby the reversing oi the direction of twist in the yarn can be :iiccomplished witl'iout disturbing the relations oi the driving tapes to their binder pulleys as is necessary in the present type of machine.

Another object is for maintaining an oven tension on the driving tapes regardless of the varying positions of the spindles in their relations to the ring rail thus preventing uneven twist in the yarn.

/Vith these and other objects in view, the invention includes the novel features of con struction, arrangement and combination of parts hereinafter described and particularly defined by the appended claims.

An embodiment of the invention is illus trated in the accompanying drawings, in which Figure 1 is a transverse sectional elevation of such parts of a spinning or twisting frame as are necessary to show the application of my invention. It shows the extreme positions of the bolster rails with reference to the stationary ring rails.

Figure 2 is a plan view of the same showing a group of spindles, their driving tape with guide pulleys, and means for taking up the slack in the tapes.

Referring to the drawings, in which like numerals indicate corresponding parts wherever occurring, 10 represents the driving cylinder, of common construction, which may be driven in any suitable manner, and 11 the spindles, each of which is provided with a whirl 12.

The spindles, arranged in two opposltely disposed rows with the driving cylinder between, are supported on rails 13 and i l fixed between two yokes 15 and 16 suspended above the cylinder by suitable means to the builder mechanism of the machine (not shown in the drawings) and reciprocated thereby. In my construction each rail supports three pairs of spindles, oppositely disposed pairs being driven by an cndlesstape 17 which passes from the underside of the cylinder upwardly and over a guide pulley 18, then around the whirls of a pair of spindles on one side, then across and under a guide pulley 19 and upwardlyaud over-a take up pulley 20, then downwardly and under a guide pulley 21, then directly across and around the whirls oi the oppositely disposed pair of spindles, then directly across and over a guide pulley 22 and thence downwardly and under the cylinder. 1 i

The guide pulleys 18 and 22 are rotatable respectively on rods 23 and 24 oppositely disposed to the centre of the cylinder and parallel thereto, the ends of the rods being supported on the undersides of the yokes 15 and 16. The guide pulleys 19 and 21 are respectively rotatable on parallel rods 25 and 26, supported on the upper parts of the yokes 15 and 16 and are parallel to and above the rods 23 and 24. The locations of the pulleys are such that the top faces of pulleys l8 and 22 and the bottom faces of 19 and 21 are in the plane of rotation of the spindle whirls. In consequence of this construction the driving tape will run equally well in either direction to give the desired hand of twist in the yarn.

The take up pulley 20 is rotatable in bearings on one arm of a lever 27 swingably mounted on a shaft 28 in a fixed relation with the framing of the machine, the proper tension being imparted to the tape running over the take up pulley by a weight 29 adj ustably mounted on the other arm of the lever 27.

My improved spindle driving mechanism was particularly designed for use in connection with spinning machines wherein the traverse of the yarn on the bobbins is efiected by the reciprocations of the spindle bolster rails 1 1 in combination with stationary ring rails 30 as is shown in the drawings but if desired my improvement is readily adapted for use on machines having stationary spindle bolster rails and reciprocating ring rails in which case the positions of the tape guiding pulleys would be in a hired relation with the driving cylinder.

1 claimi 1. A spinning machine having oppositely disposed rows of spindles, a driving cylinder disposed between them, a driving tape trained about the cylinder and about two oppositely disposed pairs of spindle whirls, and a spindle support extending transversely of the cylinder, in combination with tape guiding means mounted on said support comprising apair of tape guiding pulleys on each side of the cylinder, both pairs of pulleys co-operating with the same tape, and means p0sitioned above the cylinder for imparting tension to the tape.

2. A spinning machine having oppositely disposed rows of spindles, a driving cylinder disposed between them, a driving tape trained about the cylinder and about two oppositely disposed pairs of spindle whirls and a spindle support extending transversely of the cylinder, in combination with tape guiding means mounted on said support comprising a pair of tape guiding pulleys on each side of the cylinder, both pairs of pulleys cooperating with the same tape, a supporting member positioned above the cylinder, a lever swingably mountedon said support, a tape guiding pulley rotatably mounted in one arm of said lever and a weight adjustably mounted 011 the other arm of the lever whereby tension is imparted to the tape.

3. In a spindle driving mechanism for spinning machines, a driving cylinder, spindles at opposite sides of the machine, tape guide pulleys at opposite sides of the cylinder and means for effecting tape tension, in combination with a tape which passes under the c 'linder, over one of the tape guiding pulleys, then around the whirls of two adjacent spindles on one side of the machine, then under another tape guiding pulley, then upwardly over the tape tensioning means, then downwardly under another tape guiding pulley, then straight across around the whirls of two adjacent spindles on the opposite side of the machine, then over another tape guiding pulley and back under the cylinder.

In testimony whereof, I have signed this specification.
